|Helioseismology is a powerful tool to study the Sun’s internal structure and dynamics by using solar oscillations observed on the Sun’s visible surface. In this talk, Prof. Gizon will introduce the method and scientific questions that helioseismology aims to answer. Recent advances in the field include the discovery and characterization of inertial modes of oscillation will also be briefly introduced. The recent work on helioseismic far-side imaging, a technique that can map active regions on the back side of the Sun are also presented.
|Prof. Laurent GIZON studies solar and stellar physics. He currently serves as the managing Director of the Max Planck Institute for Solar System Research, Gottingen, Germany, where he leads the department "Solar and Stellar Interiors". He is also a full professor at the university of Gottingen. His main specialty is helioseismology, which is the use of solar acoustic oscillations to study the interior of the sun. He studied undergraduate physics in Grenoble, and aerospace engineering and astrophysics in Toulouse, France. He graduated with a PhD in Physics from Stanford University. He is involved in a number of space missions, such as the Solar Dynamics Observatory (NASA) and the Solar Orbiter (ESA). One of his main focus is to prepare for the PLATO mission (ESA), to be launched in 2026. PLATO will measure oscillations on distant stars and characterize earth-like planets around sun-like stars.
